Product Description
Hand cups use vacuum to lift and carry loads, as follows: A manual pump
removes air from between the rubber pad and the contact surface; a red line
on the pump's plunger serves as a vacuum indicator; a check valve allows the
user to repump the cup without removing it from the contact surface; and a
release mechanism allows the cup to disengage completely.
Model Pad Nominal Dia. Max. Load Capacity*
LJ6VH LJ6 6" [15 cm] 70 lbs [32 kg]
N4000, N4300, N4950 G0695 8" [20 cm] 125 lbs [57 kg]
N5000, N5300, N5450 G0725 9" [23 cm] 150 lbs [68 kg]
N5450CS, N5000CS VPCS9 9" [23 cm] 150 lbs [68 kg]
N6000, N6300, N6450 G0750 10" [25 cm] 175 lbs [79 kg]
*Maximum Load Capacity includes a 3:1 safety factor and requires the
following: attachment on clean, smooth, nonporous at surfaces; a minimum
vacuum level of 17½" Hg [-59 kPa]; and a friction coefcient of 1. This rating
is based on tests of new hand cups attached to the upper, horizontal surface
of static objects in ideal conditions. Many factors can reduce the capacity,
including: lifting a load when the cup is attached to a vertical or inclined
surface; or lifting a load that applies leverage to the cup. See www.powrgrip.
com for more information.
Load and Environmental Conditions
Use the cup on clean, relatively smooth, nonporous surfaces, at temperatures
from 10° to 120° Fahrenheit [-12° to 49° Celsius]. Moisture or contaminants
can reduce the slip resistance of the cup. The red-line indicator may not
perform reliably at elevations above 5000 feet [1524 meters]; see Service.
OPERATION
To Attach
1) Position the hand cup on the contact surface so the red line will be visible
if it should appear while lifting the load. CAUTION: Test the cup for staining
or deformation of load surfaces with light colors or soft coatings.
2) Pump the plunger until the cup attaches completely. When the red line is
hidden, vacuum is sufcient for lifting.
3) Check the plunger frequently to make sure the cup remains securely
attached. If the red line appears while lifting, set down the load immediately
and pump the plunger until the red line is hidden again (see WARNINGS).
To Release
1) Set the load on a secure support.
2) Pull one of the release tabs (on 6" [15 cm] cups) or press the valve
release lever (on other cups) until the cup disengages completely.
CAUTION: Remove the cup when not in use.
MAINTENANCE
Service
Since aging and wear reduce the capacity of the rubber pad, it should be
replaced at least once every 2 years or whenever damage is discovered (see
Inspection).
If the hand cup does not function normally, the cup face may be dirty or the
cup may require service. First clean the cup face according to the directions
to follow. If the condition persists, contact an authorized dealer or visit www.
powrgrip.com for assistance.
Cleaning
1) Remove the air lter from the cup face.
2) Use a clean sponge or lint-free cloth to apply soapy water or another mild
cleanser to the cup face; see WARNINGS and www.powrgrip.com for more
information. CAUTION: To prevent liquid from contaminating the pump, hold
the cup face-down or cover the suction hole in the lter recess.
3) Wipe all residue from the cup face.
4) Allow the cup to dry and reinstall the air lter.
Inspection
Examine and test the cup regularly to make sure it does not exhibit the
following faults:
• cuts or damage to sealing edges of rubber pad.
• cracks or dents in handle or pump.
• reappearance of red line soon after attaching cup.
• sluggishness or dramatic changes in pump action.
• excessive glaze or stiffness of rubber pad.
• air lter missing from cup face.
Correct any faults before using the cup (see Service).
Storage
Store the cup in clean, dry condition within its protective carrying case.
WARNINGS
Failure to observe WARNINGS could damage the hand cup or the load, or
cause injury to the user.
• Do not use the cup to lift loads that exceed the Maximum Load Capacity or
the effective capacity (see SPECIFICATIONS).
• Do not use the cup to support a person.
• Do not place the cup face against surfaces which could damage the sealing
edges.
• Avoid conditions that could cause the cup to slip or to disengage
prematurely, such as: contaminants, cuts or scratches in the cup face or
contact surface; applying the cup to porous materials; or applying pressure
against the cup edge.
• Do not use the cup to lift when the red line is visible. If the red line
reappears frequently, discontinue use and see Service.
• Do not allow anything to interfere with free movement of the plunger while
the cup is attached.
• Do not touch the release tabs (on 6" [15 cm] cups) or the valve release
lever (on other cups) while lifting.
• Do not attach 10" [25 cm] diameter cups to thin, fragile materials.
• Do not use harsh chemicals (such as solvents or gasoline) or unauthorized
rubber cleaners and conditioners to clean the cup.
